GRAIN-RECLAIMER.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed March 21, 1917. Serial No. 156,494.

To all whom 'it may concern.'

Be it known that I, WALTER L. IsoM, a citizen 'of the United States,residing at Crows Landing, in the county of Stanislaus, State ofCalifornia, have invented certain new and useful Improvements inGrain-Reclaimers; and I do declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawings, and to the characters of reference markedthereon, which form a part of this application I This invention relatesto improvements in grain saving device and is particularly designed forthe purpose of collecting and saving grain of `all kinds from fieldswhere the same has fallen upon the ground due to fire, winds, loss inharvesting or other causes. I aim by means ofvmy improved invention tocollect the waste grain from the ground by means of` a combinationsweeper and vacuum mechanism whereby the grain may be drawn upwardlyfrom the ground and threshed and sacked or otherwise handled as may befound desirable. I also embody in my improved invention a set of sidesweepers which move over the ground at cach side of the machine andsweep the ground in the path of the suction sweeper. By means of theseside-sweepersv a considerable area may be covered by the machine at onetime. The invention also embodies advantageous features for compensatingfor the unevenness in the ground surface and for containing the suctionwithin the mechanism without undue w-aste thereof.

A further object of the invention is to producea simple and inexpensivedevice and yet one which willebe exceedingly effective for the purposesfor which it is designed.

These objects -I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views.

power, Suspended below this carriage 1 is any desired form of supportingbraces 2 hinged to which as at 3 are two projecting arms 4. Each armahas at its outer end a bracket as at These brackets 6 have threedownwardly projecting supports 7, 8

.and 9 respectively and one upwardly proj ecting support 10. Journaledin cach of the brackets 6 near the forward end thereof is a shaft 11. @neach end of vthis shaft 11 is secured a small tractionvwheel 12 clutchedas at 13 to a pinion wheel 1% turnable on the said shaft 11. Springs 15hold these pinions 14 normally into engagement with the wheels 12 but inrounding corners or other like the clutches 13 compensate for theturning movement as is usual in this form of clutch. The pinions 14Eengage and drive the pinions 16 mounted en a small shaft 17 journaled inthe member 8. On this shaft 17 between the members 8 is mounted a rotarysweeper 18 which has motion in thc direction of the arrows shown in Fig.3. Secured to the members 7 and 9 are cross bars 21 secured to which areflexible inclosing covers 19 made of any suitable material and weightedwith shot or other similar material as at 20 so as to follow theinequalities in the ground surface and prevent an undue suction of airin and around the sweeper 18.

A cross bar 22 is secured on the members 10 and fastened to this crossbar 22 and to the front ross bar 21 is a suction hopper 23. The sweeper18 opens into the lower end of such hopper 23. Hinged to the end of thehopper 23 adjacent the cross bar 22 is an inclosing cover 24 which tsover the sweeper 18 between the hopper 23 and the rear cross bar 21.This normally incloses the sweeper 18 but may be opened if access isdesired to such sweeper for any purpose. The suction hopper 23 extendsupwardly and contracts toward its upper end where it is provided with aslip joint 25 or any desired structure to allow the rise and fall of thesweeper mechanism as it travels over the unevenness of the groundsurface. This rise and fall being permitted by reason of the hingeconnection 3. The slip joint 25 opens into the suction pump vcasing 26which may be of any desired form and wit-hin which is the suction rotor27 driven by a shaft 28 suitably journaled through the casi-ng 26 andlikewise journalcd at its upper end in a bearing 29 suitably supportedin an upright frame work 30 mountedV on the supporting carriage 1.

Secured to the shaft 28 outside of the' easing 26 is a pulley 31arranged to be driven by a belt 32 from the source of power mounted onthe carriage (not here shown). The suction pump 26 delivers through adischarge outlet 33 to any desired point preferably to a thresher orcleaner (not here shown).

The operation of the device is as follows;

y with the forward movement of the. carriage 1 lthe traction wheels 12through the ymeehanism described rotate the sweeper 18. lThis sw-eeper18 sweeps up the waste grain and di-rects the same toward the suctionhopper 23. The suction of the pump rotor 27 continually tends to createya vacuum -in the hopper 23. This draws all waste grain through thehopper and the flexible joint into the casing 26. The action ofthe rotorvanos carries the -`grain through the pump and discharges it through theoutlet 33.

In order to lcover a large area of ground with my mechanism I -provideside sweepers 34 operated by any suitable means but `preferably bytraction wheels 35 operatively connected with the shafts 36 of thesweepers 31'ina manner similar to that in which the wheels 12 areconnected kwith the sweeper shafts 17 but instead of the pinions I willuse beveled gears for the reason that the sweepers 34C are disposed atan angle to the carriage l in order to sweep the grains to a pointbeneath the carriage 1 and nthe line of travel of the sweeper 18. l

In practice it might be found that the suction of the vacuum pump alonewould be sufficient to gather up the grain. In that event, the sweeper18 could be disposed of, but in view of the fact that thel grain mightbecome lod 'ed under small clods of dfi-rt and the like I elieve thesweeper would be a valuable adjunct for the purpose of uncovering thegrain .and ,subjecting the same wish to limit myself to the use of anyspecial form thereof.

From the foregoing description it will kbe readily seen that I haveproduced such 'a device as substantially fulfils the object of theinvention as set forth herein.

Vhile this specification sets forth in detail the present and preferred`construction of the device, still in practice such deviations from suchdetail may be resorted to as to'not form a departure from vthe spirit ofythe invention as defined by 'the appended claims.

Having thus described my invention what I 'claim as new and nseful anddesire to 'secure -by Letters Patent is:

1. Agra-in reclaimer comprising a vehicle, a plurality of arms mountedforv oscillating movement relative to the vehicle. a bracket secured =toeach arm, .each :bracket having lone upwardly projecting support and aplurality of downwardly projecting supports, a suctionhop-per secured at:one lower edge-to lthe upper support and vat vthe opposite vedge to oneof the :lower supports to form a side and bottom opening into `the same,means for driving the grain into the hopper through said-opening, andmeans for applying suction to the hopper.

2. A grain reclaimer comprising a vehicle, a plurality -of arms mountedfor 4oscillating movement relative yto Lthe vehicle, a bracket securedto each arm, each bracket `having one upwardly projecting support andthree downwardly projecting supports, a suction hopper having oneedgeconnected to the upper supports and its opposite edge connected tothe foremost lower support to form a side and bottom fopen-ing into thehopper, a vbrush journa'led on vthe central lower supports and arranged-to sweep into the hopper, and flexible inclosing covers suspended fromthe front and rear lower "supports to drag along the ground and confinethe suction and the action lof the sweeper within the hopper.

In testimony ywhereof I aiiix my signature.

WALTER L. ISOM.
